SPECIFICATION formingpart of Letters Patent No. 288,199, dated November 13, 1883.

' Application filed June 9, 1883. (No specimens.)

To ztZZ whom, it may concern:

Be it known that I, FRANCIS LUCAS Brno, a citizen of the United States, and a resident of the; city of Elizabeth, Union county, New Jersey, have invented a new and useful composition of matter to be used for dry-stamping,

printing, or picturing, with perforated pat- The specimen contains the following proportions, viz: twenty-fiveper cent., in weight, of gum-dammar; twenty-five per cent., inweight, of rosin; twenty-fiveper cent., in weight, of aluminium bronze; and twenty-five per cent., in weight, of white-metal bronze.-

In using the above-namedcomposition the process is known as pouncing, and is done by placing the pattern (rough side up, if parchmentor paper patterns are used,) stencil-plate, or cut design on the material to be stamped, printed, or pictured, as the case may be,with weights placed at the corners to keep from slipping. Make a distributor by covering a small block of wood with apiece of fine felt. Place a small portion of the composition upon some hard smooth surface, and rub the distributer well into the composition, and shake off the loose powder from the distributor. Then rub the distributor over the perforations in the plates or designs until the pattern is clearly marked on the material. Then carefully remove the pattern, lay a piece of thin paper over the pictured design,and pass ahot iron over it. (For stamping on velvet hold the back of the stamped velvet. against the face of the iron until the gum in the composition is melted.) The iron should be as hot as possible without scorching the material. (Thin material maybe ironed on the back.) This will melt the gum in the composition and fasten the design to the-material. The material then, as stamped, printed, or pictured, is immediately ready for use.

This composition is applicable for goods of I all colors; is very durable, and maintains its bright and shining color. It is not affected by the heat or dampness of the weather.

A great want has long been and is now felt for some powder that will stamp dark-colored dry-goods and hold the design upon the material until embroidered. Apreparation called French oil is now generally used for this purpose. This preparation is made from white zinc and boiled linseed-oil, with a drier added, but it is troublesome to make and is dangerous to use on account of its indelible nature. The parchment pattern that has been used with it must have one ormore washings in benzine or naphtha after using, in order to free the holes from the oil, and if any of the oil is spilled, or a mistake is made in the stamping, the material may be ruined. Upon goods of alight color the common preparation used is gum and prussia-n-blue; but this is only applicable to lightcolored materials.

Many attempts have been made to use some lightcoloredsubstances other than bronze in a connection with gum for stamping with the same patterns that have before been used with prussianblue; but all such attempts fail, (see Ingalls Manual, page 9, publish ed by J. F. Ingalls, of Lynn, Massachusetts,)beoause either the prussia-n-blue remaining upon the pattern contains such strong coloring properties that when the heat .is applied it overcomes the white and robs it of its marking power, or because the white material used is destroyed by the coloring matterin the goods. My composition can be used with patterns upon which prussian-blue has been used, or any marking preparation in use, provided the patterns are dry.

, I am not aware that any composition of powdered aluminium bronze and powdered white-metal bronze have been used with gum for the purpose of stamping, printing, or picturing.

W'hat I claim, and desire to secure by Let-'
